The APEX_PWA package manages Push Notifications:

B. APEX_PWA.PUSH_QUEUE: This procedure forces immediate processing of the Push Notification queue, sending queued messages (added via APEX_PWA.SEND) to subscribed devices without waiting for the default scheduler (e.g., every 5 minutes). Example: APEX_PWA.PUSH_QUEUE; ensures a "Meeting now!" alert goes out instantly.

A. APEX_PWA.HAS_PUSH_SUBSCRIPTION: Checks if a user has an active subscription (returns BOOLEAN), not for sending.

A dynamic List of Values (LOV) in APEX populates options based on a query source. The supported types include:

Function Returning SQL Query: A PL/SQL function that returns a SQL query string (e.g., RETURN 'SELECT ename, empno FROM emp';). This offers flexibility for dynamic conditions or complex logic.

SQL Query: A direct SQL statement (e.g., SELECT ename, empno FROM emp) executedat runtime to fetch LOV values. It’s the simplest and most common approach.

Procedure: Procedures execute logic but don’t return query results in the format required for an LOV (they don’t produce a result set directly).

Importing an APEX application involves transferring its definition (exported as a .sql file):

C. You cannot import an APEX application exported from the latest APEX version to an old APEX version: APEX enforces backward compatibility limits. An app exported from 23.2 (latest features like AI Assistants) can’t import into 19.2, as older versions lack support for newer metadata (e.g., APEX_AI tables). The import wizard checks the version and rejects incompatible files.

A. You cannot change the application ID: False; the import wizard prompts for a new ID if there’s a conflict or if you choose to override.
